CARPET-SWEEPER.

Specification of Letters Patent.

Fatented Sept. 3, 1907,

Application filed February 16,1907. Serial No. 357,691.

are shown arranged at right angles to a main brush carried by a carpetsweeper casing and certain means are also shown for throwing the brushesfirst mentioned in and out of gear.

This invention is an improvement in such means, and a further object oithe invention is to provide the carpet sweeper with dumping dust pans,and means for dumping said pans by pressure oi'. the foot.

The invention consists of the novel features hereinaiter 'fullydescribed, pointed out in the claims and shown in the accompanyingdrawings, in which,

Figure l is a plan view of the sweeper. FigQZ is an end view of thesweeper casing, a guard being removed and certain shafts and bracketsbeing shown in section. Fig. 3 is a horizontal section taken through thesweeper casing and showing the interior of the said casing. Fig. 4.- isa section on the line 4 4 of Fig. 3. Fig. 5 is an end view oi thecasing, the parts being shown in elevation. Fig.V 6 is a horizontalsec-` tion taken through certain bearings arranged at the ends of thecasing, the shaft carrying the corner brushes, a friction disk carriedby said shaft and a hook member formed upon a movable bracket beingshown in plan.

In these drawings A represents a casing in which is mounted a main brushB. The casing is supported upon wheels A which are mounted upon the endsof rods A3 which extend through the casing and are connected to the samemidway their ends by brackets A4. The outer end portions of the rollerupon which the brush B is carried are provided with small frictionwheels B which rest between the wheels A at each end oi the casing andare rotated by engagement with said wheels. The rods A3 pass looselythrough the ends of the casing and are permitted a slight play so thatthe brush B will rotate in the proper direction according to thedirection in which the casing A is moved.

At each corner of the casing are small brushes which are mounted atright angles to the brush B and are designed to rotate soas to throw thesweepings into the path of the brush B. The brushes C correspond to thebrushes F shown in the patent above referred to and the brush Bcorresponds to the similarly designated brush shown in the said patentand to which reference is had.

Upon each end of the casing A are pivoted at D5 two sets of levers D,said levers being arranged upon opposite sides of the wheels B and'substantially in avertical position. The upper ends oi these levers areconnected together by means of links at opposite ends of the casingwhich are connected by a bail D2 the ends of which are pivotallyjournaled in the links midway the ends of the links. The bail carries ahandle D3 and is also engaged, by locking plates D4 65 arranged atopposite ends of the casing which plates have a compound curved edgeengaging the end portions o the bail as the handle is swung from oneside of the casing to the other, and by their frictional contact serveto loclcthe bail and handle against accidental movement from one side ofthe casing to the other.

The brushes C are mounted upon shafts E which are journaled at theirinner ends in movable brackets F.

These brackets are substantially triangular in outline, 7 5

the central portion being cut away, the apex of each bracket is extendedto form hook members F which project toward the levers D and engage thelower ends of said levers. The apex portion oi each bracket is alsoslotted as shown at F2 and through said slot passes a rod 80 A3 whichlimits sliding movement oi the bracket. In the `apex portion oi eachbracket is also formed a bearing box F4 in which boxes are mounted insuitable ball bearings the inner ends oi the shafts E.

Upon each shalt E and within the cut out portions ol the brackets F aremounted friction disks F5, said disks l being fixed to the shafts E andadapted to engage the peripheries of the Wheels A which are preferablyprovided with rubber tires. 'The shafts E are also supported by bracketsG which are carried by the sides of the casing A and project beyond theends or' the casing. The brackets G carry upon their inner laces sleevesG2 in which slide sleeves F6 carried by the brackets F and which holdsuitable ball bearings F7, Within which the shafts E rotate, the saidshaits also passing loosely through the brackets G. The brackets Gr areconnected at each end oi the casing by end braces G which not only serveas guards for the projecting ends o the rods A3 but also furnishbearings or stub pins IzI which fit Within the casing A and into thefriction wheels B. upon opposite sides of the brush B are arrangedpivoted trays J, which receive the sweepings from the Ibrush B, thesides oi the trays adjacent the brush carrying the pivot pins and thesides opposite the brush dropping during the dumping operation. At oneend each oi these trays J has pivoted to it a curved rod I which carriesa straight outwardly proj ecting portion J2 which is angled as shown atJ3 to provide a support for the foot and the rods J have connected tothem at the upper ends of the curved portions ends of a spring Wire J4which are secured midway its ends by any suitable means to one end ofthe casing A. By depressing with the foot one ol the rods J, the dusttray connected to the lower end of said rod is swung upon its pivotalpoint and its outer edge falls, thus dumping the sweepings collectedupon said tray. As soon as the ioot pressure is released the spring J4will return it to its normal position.

The operation of the parts above described are as follower-With thehandle D3 in the position shown in Figs. l and 2 the casing A whenpushed by said handle in advance of the person using the sweeper wouldcause the brush B to rotate in the direction shown by the arrow and willcause the brushes C in advance of said casing to rotate in the directionshown by the arrows applied to them. The brushes C upon the oppositeside of the casing would be inoperative Vas their rotation would only bedesirable when the direction oi the movement of the casing was reversed.It will be observed that when the handle D3 i's in the position shownthe lever D adjacent the brushes C to be rotated will be thrown into theposition shown in Fig. 2, that is that their lower ends inclinerearwardly and as these ends are in engagement with the hook members Fof the brackets Fin which are journaled the rollers E carrying the saidbrushes C and as such brackets have a sliding movement by reason of theslots F2, the said brackets will be moved by the levers D toward thebrush, which movement of the brackets will produce a correspondingmovement upon the part of the shafts E, and this movement will bring thefriction disks F5 into engagement with the forward wheels A withresulting rotation of the brushes C. When the sweeper is moved in theopposite direction the movement of the parts will be reversed,.sincethose parts that have been in advance of the casing during the previousmovement would now be in the rear of the casing, and the wheels A/ andbrushes G which were iront wheels and brushes will become rear wheelsand brushes. The drawing back of the handle, therefore, will shift themechanism shown at the end of the sweeper in the drawing so that thefriction disks F5 which had been out of engagement with the wheels A asmentioned in the first part of the operation, would not be brought intoengagement with said wheels and the brushes O shown upon the left handside of the various figures would be rotated while the brushes C whichhad formerly been in operation, would become idle through thedisengagement of the friction disks mounted upon their shafts becomingdisengaged from the wheels A coperating with'them.

Having thus fully described our invention, what we claim as new anddesire to secure by Letters Patent, isz- 1. In a carpet sweeper, awheeled casing, a main brush,

corner brushes at right angles to the main brush, shafts upon which.said corner brushes are mounted, slidable brackets in which said shaftsare journaled, friction disks carried by the shafts adapted to bebrought into engagement orremoved from engagement with the sweeperwheels as the brackets are shifted, means connected with the casing forshifting said brackets to bring said disks alternately into suchengagement as the sweeper is moved tin opposite directions, and a bailhaving a handle and connected with said shifting means to move thesweeper and shift the brackets.

2. The combination with a wheeled casing, a main brush, supplementalbrushes at right angles to the main brush, movable brackets at the endsof the casing, shafts supporting the supplemental brushes, and journaledin said brackets, friction disks carried by said shafts andv adapted toengage the wheels of the casing, pivoted levers adapted to shift saidbrackets, the levers shifting the brackets at each end of the casing inopposite directions, a link connecting each set of levers, a bail havingits ends mounted in said links and a handle connected to the bail as andfor the purpose set forth.
